An abandoned secret “horror bunker” was discovered in China near Anda in the Heilongjiang province.
It was revealed in the underground bunker that Japanese scientists conducted gruesome biological experiments on humans during World War II, including exposing their captives to anthrax bombs, frostbite, and dehydration.
According to the South China Morning Post, the facility’s existence and exact location were confirmed a week ago, even though it has been known for nearly eight decades.
The bunker, a largely U-shaped building with dimensions of around 108 feet long by 67 feet wide, was made up of interconnecting chambers and tunnels, including what archaeologists thought were labs, observation, dissection rooms, and holding cells for human test victims.
The underground location has defenses. It was constructed underground to retain privacy and provide protection during air attacks, and the test field was also surrounded by barbed wire.
The institution was managed by Unit 731, a division of the Japanese Imperial Army, which occupied China from 1931 to 1945. From 1935 until Japan’s capitulation in 1945, the unit is commonly believed to have conducted terrible biological and chemical warfare experiments on Chinese, Korean, Russian, and American POWs.
According to a story published on Tuesday by Live Science, scientists from Unit 731 were responsible for the deaths of up to 12,000 men, women, and children through their research and testing of grenades, bacterial bombs, flamethrowers, and chemical weapons.
Additionally, victims were vivisected without anesthetic, lethally assaulted with X-rays, injected with animal blood, dehydrated, and imprisoned in low-pressure tanks until their eyeballs exploded.
Additionally, Unit 731 was responsible for cultivating plague-infected fleas and releasing them over Chinese towns via low-flying aircraft. The unit’s actions caused illness outbreaks that resulted in tens of thousands of deaths.
Another test involved attaching people to wooden poles and spraying them with anthrax bombs to assess the potency of weaponized microorganisms.
To end the war, the United States dropped two atomic bombs on Japan. Estimates of the death toll are between 129,000 and 226,000 people.
